Cassettes & Freewheels for Bikes

To keep your gears smooth and running, keeping the optimum condition of cassettes and freewheels are important. They are fitted on the rear wheel, and give a high gear ratio, typically between seven and ten cogs. For mountain bike, 7-speed, 8-speed, or even 9-speed cassettes are essential, but Shimano and SRAM also introduced new 10-speed systems. For road bikeCampagnolo manufactures, 8-speed to 10-speed cassettes are the best way to go!
